Chiral Nanophotonics and Control of Light-matter Interaction

Chirality, a fundamental symmetry property, denotes the intrinsic handedness of an object, rendering it non-superimposable onto its mirror image via translations and rotations due to the lack of inversion symmetry. This property extends beyond tangible entities to include light, giving rise to a field of chiral nanophotonics. Chiral nanophotonics studies how chiral light interacts with chiral matter at the nanoscale. Understanding chiral light-matter interaction holds the key to novel applications, spanning from ultrasensitive chiral molecule sensing to quantum information processing. We introduce important concepts and recent efforts in chiral nanophotonics and its application.
